Snapshot: This week in pictures

It's not as easy as you might think to snap a clear shot of suspended Sen. Mike Duffy coming and going from the Ottawa courthouse, as Ottawa Sun photographer Tony Caldwell did Wednesday. â€śDuffy has not really taken the same route into the courthouse all week so it keeps you on your toes,â€ť Caldwell says of his battles this week. â€śAs soon as Duffy gets dropped off from his daily ride, the chase is on. Elbows up and into the pile you go hoping to come away with a great and unique photo every day as you battle cameramen, photographers and reporters.â€ťâ€‹ Tony Caldwell/Ottawa Sun/Sun Media
